Subtract the sum of xy(− x − y −1) and (xy x y) 2 2 − from ( ) 2 2 4x xy −

Answers

Answer 1

Answer:

6x + 6y -xy + x^y + xy^2

Step-by-step explanation:

Sum of xy (-x - y -1) & 2 (xy + x + y)

[ xy (-x - y -1) ]  + 2  (xy + x + y)

-x^2y - xy^2 - xy + 2xy + 2x + 2y

2x + 2y + xy - x^y - xy^2

Subtract from 2 (4x + 4y) , ie 8x + 8y

8x + 8y - (2x + 2y + xy - x^2y - xy^2)

8x + 8y - 2x - 2y -xy + x^y + xy^2

6x + 6y -xy + x^y + xy^2

Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
UThe amount of change drent for the percent increase and the percent decrease
UThe ratio of the percent increase is not the same as the percent decrease.
OThe ratio for the percent increase has a smaller denominator than the percent decrease.
U The ratio for the percent increase has a different numerator than the percent decrease.
O The original amount for the percent increase is different from the original amount for the percent decrease.

Answers

Answer:

work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

General Formulas and Concepts:

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3(4x - 5) - 4x + 1 = -6

Step 2: Solve for x

Distribute 3:                    12x - 15 - 4x + 1 = -6Combine like terms:       8x - 14 = -6Isolate x term:                 8x = 8Isolate x:                          x = 1

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    3(4(1) - 5) - 4(1) + 1 = -6Multiply:                               3(4 - 5) - 4 + 1 = -6Subtract:                              3(-1) - 4 + 1 = -6Multiply:                               -3 - 4 + 1 = -6Subtract:                              -7 + 1 = -6Add:                                     -6 = -6

Here we see that -6 does indeed equal -6.

∴ x = 1 is the solution to the equation.

Micah rows his boat on a river 4.48 miles downstream, with the current, in 0.32 hours. He rows back upstream the same distance, against the current, in 0.56 hours. Assuming his rowing speed and the speed of the current are constant, what is the speed of the current?

3 miles per hour
8 miles per hour
11 miles per hour
14 miles per hour

Answers

Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56

0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11

Therefore, the speed of the current is 3 miles per hour. Answer is 3 miles per hour

Answer:

- 0.6

Step-by-step explanation:

Start point: (5,6)

End point: (-5,12)

rate of change = (12-6) / (-5-5) = 6/-10 = - 3/5 = - 0.6

Answer:

The rate of change is -0.6

Step-by-step explanation:

Given

[tex](x_1,y_1) = (5,6)[/tex]

[tex](x_2,y_2) = (-5,12)[/tex]

Required

Determine the rate of change

The rate of change means the slope (m) and it is calculated as thus:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{12-6}{-5-5}[/tex]

[tex]m = \frac{6}{-10}[/tex]

[tex]m = -\frac{6}{10}[/tex]

Simplify the fraction

[tex]m = -\frac{3}{5}[/tex]

[tex]m=-0.6[/tex]

The rate of change is -0.6
